"Let us say that I am a photon.
I can be in 0 rest-mass, I am (maybe) forever young, but do I have a 0-size?
If I have a 0-size then I cannot be found as a center of any place, which is not itself a 0-dim_place".
A real 0-dim_place cannot be observed by any measurement tool and we have no information about it.
Since Light is a measurable phenomena where position and momentum are its complementary properties, we can conclude that time itself is under the laws of Heisenberg uncertainty principle, which is deeply connected to
h plank constant.
In short, the speed of light depends on the quantum duality (wave/particle or momentum/position) properties of the photon.
First let us start by examine some today's physics points of view of what is called a field and a particle.
If I am not wrong then the concept of a field is used to describe the common foundation of some particles with particular properties.
Each particle which belongs to some distinguished collection of properties, its existence is first of all based on its interactions with its particular field.
It means that no measurable particle is totally separated from the other measurable particles that share the same field.
If each particle is also its own field, then a collection of particles cannot have more then one particle, which is not the case by today's physics.
"
We should mention two possible points of confusion. Firstly, the aforementioned "field" and "particle" descriptions do not refer to wave-particle duality. By "particle", we refer to entities which possesses both wave and point-particle properties in the usual quantum mechanical sense; for example, these "particles" are generally not located at a fixed point, but have a certain probability of being found at each position in space. What we refer to as a "field" is an entity existing at every point in space, which regulates the creation and annihilation of the particles" (
http://en.wikipedia.org/wiki/Quantum_field_theory )
So, quantum particles are described by momentum/position or wave/particle duality.
A Langauge which is based on excluded-middle reasoning is not (in my opinion) the appropriate language to deal with quantum phenomena.
In an
excluded-middle reasoning two opposites are
simultaneously contradicting each other, and the result is
no middle.
In an
included-middle reasoning two opposites are
simultaneously preventing/defining each other, and the result is
a middle.
The best known example is the duality of a photon, which has both a wave and a particle properties that preventing (the measurement of its accurate place prevents the accurate information about its momentum, and vise versa) and defining (one property cannot exist without the other) each other.
For example, please see this picture:

As you see the two black profiles and the white vase are clearly
preventing/defining each other.
Please also see
http://www.geocities.com/complementarytheory/CompLogic.pdf , which is a short paper of mine on
included-middle reasoning.
In short, in my opinion, we cannot ignore QM , if we want to find the accurate speed of light.
